Victoria Beckham has previously faced criticism for her super-skinny frame, but this time, it's not her figure that is coming under fire.

The singer-turned-fashion designer made headlines after her runway show at New York Fashion Week, which saw a number of incredibly thin models strut their stuff down the catwalk.

The 41-year-old mother of four shared a variety of behind-the-scenes images from her show, during which husband David Beckham and Vogue editor-in-chief Anna Wintour were both seated in the front row, and is facing heavy backlash on social media for her choice in models. She also picked newcomer Peyton Knight, who is just 17 years old, to close her show (to note: Knight also walked in Alexander Wang).

Beckham's Instagram has since become the subject of a body image debate, and the U.K.'s Guardian contacted Lorna Garner, chief operating officer of the eating disorder charity b-eat who said that "these type of images do not cause eating disorders but they escalate and exacerbate existing conditions. There is overwhelming evidence that points to these images having a very negative and damaging effect."
